Since industrial processes, motors and machines are not fully efficient, they release heat as a byproduct. When you fail to get rid of the heat, it accumulates with time, thus lowering production times and even equipment breakdowns. Incorporating cooling into the process is crucial to avoid such issues. Besides, adequate cooling is crucial in various industries, including bakery, beef processing, milk processing, brewery, poultry processing, feed mills, chemical, metal, pharmaceutical, plastic manufacturing, and construction. Use of chillers is essential in these industries for cooling purposes. Industrial chillers uses glycol as the heat transfer solution to convey heat from one location of the processing line to another. Therefore, it is vital to carry out regular monitoring of the fluid to ensure optimum functioning. In this post, we explain the best way to test glycol with your industrial chiller. Glycol Industrial chillers use glycol solution in the transfer of heat. Glycol is a chemical compound with low volatility characteristics at room temperature, although you can find it as vapor or air. This slightly thick and translucid compound is crucial in refrigeration. Glycol is eco-friendly and has distinctive properties that make it suitable for the food and beverage industries, unlike other refrigerants. Glycol comes either as propylene glycol or ethylene glycol. Most industrial applications use ethylene glycol since its more economical. On the other hand, propylene glycol tends to become more viscous at very low temperatures and typically used near food. How to Test Glycol One of the best practices when using a glycol cooling system is regularly test the heat transfer solution. The recommended tool to analyze the fluid is a Misco Products Refractometer, model 7084VP (°F). A refractometer typically checks for the refractive index, which describes the speed through light travel via a material. It measures the angle at which the light seems to bend and converts it into concentration. You only require adding a few drops of the glycol on the prism, and you won’t need to adjust the fluid temperature. After that, you can read the screen readings that represent the anti-freezing point of the glycol concentration. Applications and Locations When checking the percentage, you have to consider the chiller’s environment and location. The percentage of glycol tends to reduce for chillers in an indoor location with zero possibility of freezing. But if the chiller is in an outdoor environment and temperatures are low, the percentage of glycol tends to be greater. Note that location and environment are critical considerations when choosing the correct mixture of glycol/water for the chiller process. You will need more glycol if your system is in an outdoor environment where low temperatures might freeze the fluid and cause the bursting of pipes. But a process in a completely indoor environment where there are zero chances of freezing does not require much glycol. Other Best Practices When using glycol concentration, you must be careful not to go for the automotive-grade anti-freeze. These glycol types are not suitable for industrial purposes and could cause havoc to your heat exchanger and affect heat transfer. While it might be tempting to use different glycol brands or types, the mixture can clog filters or cause gelling. If you intend to change the type you have been using in your system, ensure thorough cleaning to eliminate the current fluid. Importance of Industrial Chillers There are numerous benefits of using chillers, including consistent temperature and pressure to the process. Elimination of temperature and pressure variables leads to optimization and convenience in the process development, thus giving a high-quality product. An industrial chiller differs from wasteful one-time pass-through systems by allowing recirculation of the cooling liquid. Therefore, it increases productivity and also saves on cost. Maintenance To extend a chiller’s life and lower the costly downtime, you need to use a fluid filter and perform fluid maintenance. Besides, maintaining a proper balance of the heat transfer solution and filtration of dirt out of the system is necessary to receive more years of service from an industrial chiller. You can identify leaks along the system using food coloring but ensure it is FDA approved. Additionally, you need to have glycol in your hand in case anything happens in the process.

Chillers differ in that some transfer heat to the surrounding environmental air and some transfer heat to a water source, such as a cooling tower. Air-cooled chillers and water-cooled chillers each have their own pros and cons, and you should do your research to determine which type meets your needs better. If some of the following criteria applies to you, an air-cooled chiller is probably your best bet. You Have A Water Shortage Water-cooled chillers require sufficiency of water to run, which makes them a poor choice in areas that have water shortages. In areas with drought conditions, you may run into restrictions on the use of water-cooled systems as well. Air-cooled chillers don’t use water, so you don’t have to worry about wasting water. They do require a continuous flow of fresh air because they operate by using a condenser that’s cooled by surrounding air. That’s why you shouldn’t position them near walls that block air flow. You Want Low Maintenance Costs Compared to water-cooled chillers, air-cooled chillers don’t require much maintenance. That’s because they don’t have cooling towers and evaporative condensers that require water treatments. The trade-off is that they often have shorter lifespans than water-cooled chillers. You Want A Lower Upfront Cost Air-cooled chillers have a smaller initial investment than water-cooled chillers because they don’t have components of water transmission. Cooling towers and condenser water pumps jack up the cost of water-cooled chillers. Air-cooled chillers also don’t use water, so you won’t have to pay a higher water bill. You Have A Large, Airy, Open Space Air-cooled chillers need continuous fresh air to run, and they don’t do well placed next to each other or by other air-obstructing objects. Obstructed air flow creates problems with re-circulation and adversely affects the chiller’s performance, which is why the chiller can’t have higher walls surrounding it. If your building code requires that you have outdoor walls, you would be better off choosing a water-cooled chiller. Ideal places to put air-cooled chillers include parking lots and rooftops. You Don’t Have A Mechanical Room Air-cooled chillers need open spaces, but water-cooled chillers require mechanical rooms because of their equipment. Adding a mechanical room to a property is more costly than just choosing an air-cooled chiller. You Don’t Mind Some Noise All chillers transmit sounds, but air-cooled chillers use fans that make noise. If noise is an issue for you, you might want to go with a water-cooled chiller. Not all air-cooled chillers make the same level of noise, however, because they don’t all use the same fans. You’re Willing to Accept Higher Energy Bills Air-cooled chillers don’t do as well as water-cooled chillers in terms of efficiency. This is because dissipating heat to the air takes a lot of energy. Unfortunately, this means you’ll pay a higher energy bill using an air-cooled chiller. You Want An Easy Setup Water-cooled chillers are more complicated to install because they have more parts. Air-cooled chillers take less time to get up and running, and they’re also easier to operate. In general, neither air-cooled or water-cooled chillers are better, but you’ll want to have the type that’s best for your situation. If you’re still unsure of which type to rent or buy, you should contact the vendor for more information. At J.C. Younger Company, we offer chiller rentals to all kinds of industries.

Pharmaceutical chillers are important parts of the drug-manufacturing industry. Nearly all medicines require chilled water in their manufacturing, from antibiotics to complex cardiology medications. Chillers provide precise control over the water-chilling process, and pharmaceutical chilling plants have 15 to 1000 tons in terms of cooling power. Pharmaceutical chillers come as central process chillers and compact process chillers. Central process chillers can handle 10 to 200 tons, and compact process chillers work well for 1 to 40 tons. Compact process chillers are smaller, which makes them ideal for small spaces. All pharmaceutical chillers feature components that include evaporators, pumps, refrigerant relief valves, cooling towers and pipes, condensers, compressors, filters, fans, and tanks. They come with either an air or water condenser. Four Main Types of Pharmaceutical Chillers Reciprocating These chillers come with a water or air condenser, reciprocating compressor-motor assembly, an expansion device, control panel and wiring, a compressor motor-starter, interconnecting refrigerant piping, auxiliaries, and oil and refrigerant charge. They’re a common type of chiller, and manufacturers have improved them quite a bit over the years. When it comes to size, you can find many models that fit through a 30-inch door. Reciprocating chillers have many advantages. Manufacturers offer them in capacities of up to 200 tons. They’re easy to use with modern designs and controls, and since they’re common, users can find technical support for them without much hassle. They can use environmentally acceptable refrigerants, and many reliable manufacturers sell them. Screw-Driven Chillers Screw-driven chillers with screw compressors usually have capacities of under 300 tons. They’re called positive displacement devices because they compress refrigerant by reducing the refrigerant chamber’s size. The screw compressor squeezes two rotating helical rotors that compress the refrigerant. These chillers come in sizes of up to 40 percent smaller than centrifugal chillers, which is one of their advantages. They also have a quiet operation due to the fact that they have rotary motion and not many moving parts. Centrifugal Like reciprocating chillers, centrifugal chillers are very common with more than 80,000 in operation in North America. Their evaporator functions as a heat exchanger to remove heat from chilled water. The heat then boils refrigerant to change it into gas form. The compressor assembly consists of a centrifugal compressor and a prime mover. Centrifugal compressors are non-positive displacement type compressors, which change kinetic energy into pressure to raise the refrigerant’s temperature. The condenser also acts as a heat exchanger to take heat away from the refrigerant, which changes the refrigerant into a liquid. Heat gets redirected to condenser water and then to a cooling tower. Once turned into liquid form, refrigerant passes through an expansion device. Absorption A heat source provides absorption chillers with the energy to cool water. These chillers use water as the refrigerant and lithium bromide as the absorbent. The absorption process is thermochemical rather than mechanical, and it occurs inside a vacuum, which allows water to boil at a lower temperature. The heat source is a direct heat source from natural gas or an indirect heat source from waste heat, steam, or hot water. Double-effect absorption chillers recycle some of the waste heat produced, which makes them more efficient than single-effect absorption chillers. These chillers can handle a volume ranging from 4.5 tons to several hundred tons of cooling. Turn to J.C. Younger Company to rent quality pharmaceutical chillers.

It is officially Summer. If you want to get the most out of your equipment during the hottest months of the year, it is important to understand how hot weather can affect your chiller as temperatures heat up. Monitoring a few key performance issues on your chiller should become part of your hot weather routine: Condenser Check the clearances related to your chiller’s condenser.  If too much hot air is traveling through the condenser, pressure will build. This can cause a certain built-in safety features to activate, the high/low switch. Condenser tubes can be cleaned by hand or use of a chemical based cleaning method. Significant performance reduction can be caused even by scale build up that is quite thin and seemingly irrelevant. Air Flow As air flow diminishes, pressure rises. Once the pressure reaches a high enough level, the high/low switch will be tripped. Determine that the space around the chiller is providing adequate airflow. Warmer air expands. As ambient temperature heats up around your chiller, you may need to adjust its position to provide more space for air circulation. If it is too near a surface, such as a wall, as the hot air is expelled, the area between the chiller and the wall will heat up quickly. Allow enough space for discharged hot air to dissipate effectively. Inspect fan blades, motors and blowers and determine that all are operating properly and have no obstructions. High/Low Switch This safety feature is designed to protect the chiller’s compressor from damage or failure due to high pressure. Once activated, the chiller will have to be reset manually. Rather than have an automatic reset design, the manual reset requires an operator to determine that the high pressure problem has been resolved. There are other issues other than high ambient temperatures that can result in high pressure that will trip the high/low switch: Malfunctioning fan motor Reduced air flow Condenser blockage Rapid glycol temperature increase due to sudden high load Once the high/low switch has activated the compressor is no longer running. The chiller’s pump may be running and distributing glycol but the compressor will not run until the high/low switch is manually reset. Regardless of the function of your chiller (brewery, foodservice, medical field, industrial), the principles of how the machine operates are the same. Chillers require proper monitoring and maintenance, especially during the hottest season of the year, in order to operate at optimum efficiency. A non-operative chiller can interfere with a business or industry’s productivity. A qualified technician may not be immediately available. To avoid operational disruption of your chiller and the resulting down-time it could cause, the best solution is to rent a chiller from a qualified company. By renting your chiller you enjoy the following advantages: Replacement unit without investing thousands of dollars Easily upgrade or downsize according to need Rapid response for unit delivery Professional maintenance Dependable, reliable, round the clock service Rental agreement protection for damage as well as normal wear and tear When selecting your chiller, the key to success is the company you choose.

Because industrial chillers can be used for such a wide variety of applications, it can be hard to know the right set point to use to achieve the ideal temperature for your needs. Especially when you are renting a chiller and haven’t used one before, you may have questions about the proper temperature or temperature range. Each industry and product can vary, so it’s a good idea to do your own research and talk to us about your individual needs. However, there are some standards to keep in mind for common applications that may help you decide on the right chiller model. Breweries and Wineries Chillers are commonly used in the beer and wine industries to keep beverages fresher for a longer time. The cold temperature can help the fermentation process and preserve the taste in storage. In brewing, oxidative reactions won’t make the beer go bad, but they can have definite effects on the flavor. You can’t keep oxidation from happening, but keeping beer cooler will slow down the reaction and preserve the intended flavor for longer. Most breweries set chiller temperatures between 28 and 30 degrees Fahrenheit, but a low gravity beer that has less fermentation may begin to freeze at this setting. You’ll need to check regularly to ensure that your beer is cool without any ice formation. Wine requires the proper temperature for fermentation so the process can be made consistent throughout several batches. Varied temperatures during fermentation can lead to vastly different results — never a good thing for a winemaker. Typically wineries use temperatures between 30 and 35 degrees for fermenting and can go even lower for cold stabilizing. Agriculture Many companies in the food and dairy industries use chillers to cool water for processing, preserve milk and other easily spoiled products for longer life and keep produce cooler after harvesting. Food-related applications generally require temperatures of anywhere from just below freezing (31 degrees) to properly freeze produce to between 32 and 55 degrees for cool storage of fresh fruits and vegetables. In the dairy industry, rapid cooling of milk and milk products is an important need. Milk comes out of the cow at over 95 degrees and must be cooled to and stored at around 38 degrees for ideal quality and low bacteria counts. Medical and Pharmaceutical Industries Medical researchers use chillers to maintain consistent, low temperatures during experiments. Temperatures can range from a few degrees below room temperature to extremely low — up to -40 degrees. Expensive medical equipment that can easily get overheated also can use chillers as a primary or backup cooling mechanism. Temperature setting depends on how often the equipment is used and for how long, how it is housed and what the ambient temperatures are. Generally, temperatures of between 45 and 50 degrees are suitable for cooling equipment. Pharmaceutical uses include use of chilled water in manufacturing and cool storage. Usually, 35 to 46 degrees is the recommended temperature for refrigeration during transport and storage of most cold-chain medications. Data Centers Maintaining expensive servers and other computer equipment is easiest if temperatures are consistent. To cool these heat-producing machines and keep them at peak performance, temperatures between 68 and 71 degrees are ideal. The size of the room and the number of servers will help you determine the best temperature. The American Society of Heating, Refrigerating and Air Conditioning Engineers recommend that 81 degrees is the absolute highest that temperatures should reach. Other industries can utilize chillers to keep expensive equipment cooled to a specific temperature, to cool liquids needed as part of processing or in the manufacturing process, such as to cool plastics.
